Description

A Simple Positioning Device for Measurement of Leaving Water Radiation

technical field

The invention relates to the technical field of ionizing water radiation measurement devices, in particular to a simple positioning device for ionizing water radiation measurement.

Background technique

Water-leaving radiation refers to the radiant energy that leaves the water surface after the radiant energy enters the water body and undergoes absorption, scattering and transmission effects with the water body. Since the water-leaving radiation contains the information of the water body, it has become an important physical quantity in the study of water quality remote sensing.

Portable field spectrometers are usually used to measure water-leaving radiation on the water surface. At present, when measuring, it is necessary to hold a pole and tie a spectrometer probe to one end. In order to meet the observation geometry required by the code, the spectrometer probe is positioned by visual estimation. The accuracy of this visual estimation positioning method is very poor. In addition, due to the two-way nature of water-leaving radiation, there are great differences in water-leaving radiation at different angles. For the measurement of water-leaving radiation at multiple angles, the traditional simple measurement of visual estimation and positioning cannot be used.

Angle measurement and positioning in X, Y, and Z three-dimensional spaces are realized through three angle measurement devices. When in use, the rotation angle of the crossbar in the horizontal plane is generally measured. At this time, the first angle measuring device and the second angle measuring device are required to measure the angle to ensure that the crossbar does not tilt forward and backward in the direction of the longitudinal section, and does not tilt left and right in the cross section. Rolling, at this time, the rotation angle value of the crossbar in the horizontal plane is measured by the third angle measuring device. Among them, the first angle measuring device and the second angle measuring device both include a dial, a bearing concentric with the dial, and a plumb suspended on the bearing and connected by a string. The plumb is difficult to carry, and the string connecting the plumb is easy to wear. And it is not easy to replace. In addition, there are bearings on the two angle measuring devices, which will also wear out during use, and are not easy to replace and maintain.

Therefore, on the basis of ensuring that the multi-angle positioning device accurately measures the rotation angle of the crossbar on the horizontal plane, how to solve the problems of inconvenient portability and maintenance are urgent technical problems to be solved by those skilled in the art.
